    circumstances possesses the properties which we de- scribe by the word zinc, is no doubt contained in the sulphate, but with different properties, and in the chloride with properties diiTerent from either; so also of the compound radicals. It is to be hoped that we may soon be able to give an account of the nature of the processes by which these changes of properties are effected ; but that task can only be entered upon when we have obtained exact determinations of the relative momentum of atoms in various compounds, the proportion of which to their masses determines their physical and chemical properties. ON GERHARDT'S DISCOVERY OF ANHYDROUS ORGANIC ACIDS* THE discovery by M. Gerhardt of a number of anhydrous organic acids has thrown so much light on one of the most important questions of chemical philosophy, that it constitutes one of the most remarkable illustrations of the manner in which the rich materials of organic chemistry may be brought to bear on the explanation of the pheno- mena of chemical action and the laws of chemical combination. It is not unworthy of remark, that the bodies pre- * [From Notices of the Proceedings at the Meetings of the Members of the Royal Institution^ vol. i., 1851-1854, pp. 2'^q-242.] D
